There are three bugs in this code:
1) If indx_get_root() fails, then return -EINVAL instead of success.
2) On the "/* make root external */" -EOPNOTSUPP; error path it should
free "re" but it has a memory leak.
3) If indx_new() fails then it will lead to an error pointer dereference
when we call put_indx_node().
I've re-written the error handling to be more clear.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
